* overlapping sweeps can never double-dispatch a task. One member executes at

- If the output is a document, spreadsheet or presentation, generate a real file (renderDocx / renderXlsx / renderPptx or the docx/pptx/xlsx skills) and register it with team_tasks(action="attach", taskId=%s, name="<file name>", url=<the download link the render tool returned>). Keep the result a summary — do not paste file contents.
